| Abstract |
Output-voltage remote sensing is typically used to improve static voltage accuracy at the point of load as well as to improve the load transient response. Every switched-mode converter has its unique dynamical profile, which may definitively change due to adding of extra impedances into the converter, when the output-voltage remote sensing is applied. A typical effect of a pure cable connection is an increase in the capacitive-load sensitivity especially at high frequencies. Resonant-type impedances may have more profound effects making the converter more sensitive to other types of source and load interactions. The paper provides consistent methods to analyze the impact of remote sensing based on a general two-port model of an electrical voltage-output system. Buck converters are used to provide practical evidence. |
